DRAFT-RIGGING FOR RAILWAY-CARS.

Specication of Letters Patent.

Application filed July 2 2, 1912, Serial No. 710,839. Renewed April 5,1915. 'Serial No. 19,333.

T0 all whom t may concern.'

Be it known that I, WILLIAM H.,M1NER, a citizen ofthe United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Draft-Rigging forRailway-Cars, of which the following is a full, clear, concise, andexact description, reference being had to .the accompanying.

enlarged details; Fig. 3 being an elevation partly in longitudinalsection of the friction shell and contained parts shown in the state ofcompression; Fig. 4 a front end view `of the compression resistingmember; Fig. 5 a perspective view of one of the shoes; Fig. 6 aperspective view of the wedge; Fig. 7 a perspective view of one of thefriction rollers; and Figs. 8 and 9 perspective views of the disks.

In the drawings 10, 10 represent a draft sill or parts of the car frameto which the draft rigging is attached, 11, 11 the stop members, 12 thedraw bar carry iron, 14 the end sill, 15 the buffer block, 16 the drawbar, 17 the draft yoke, 18 the frontfollower, 19 the tie plate and draftyoke carry plate; all of said parts being of well known construction,and serving their usual functions.

2O is the compression resisting member consisting of the friction shell21 and the parts contained therein, hereinafter more specificallyenumerated. The friction shell is open at its front end 22 and closed atits rear end 23 by the member 24, which is preferably integral with thefriction shell 21,

` and performs the function of ,a rear follower. The shell is externallyprovided at its rear end with the recess 25, the walls forming saidrecess providing inside the shell the boss 26 around which the outerspring 27 is seated against the rear inner face 28 of the' frictionshell, the boss being) provided at its inner end with the seat 29 forthe inner spring 30. The friction shell vthe transverse shoulders 36,36.

each of the wedge faces 35 and the friction face 33 of the adjacent shoeis placed i Aportion thereof, so constructed as to form the circularshoulder 40 against which the rear disk is seated upon the fullcompression of the springs 30 and 27. The member 24 at the rear end ofthe shell 21 is hollow about the boss 26, thus permitting the spring 27to be of exceptional length.

The wedge 34 is provided with the recess 41 to receive the head 42 ofthe connecting rod 43, which passes through the opening 44 in-the wedge,rearwardly through the openings 45 in the center of the disks 39, 39,and the opening 46 in `the rear central portion of the shell into therecess 25, which is of suitable dimensions to receive the nut 47. Innormal position the parts within the friction shell are in the relativepositions illustrated in Figs. 1 and 2 of the drawings. The disks 39, 39are of suitable strength so that upon the compression of the gear thesaid disks and the springs 30 and 27 are fully compressed, and the reardisk is in engagement with the shoulder 40 of the shell before the saiddisks are in a position resistance'afforded by the frictional engagementof the friction shoes with the internal friction face of the shell thereis added the l resistance of the disks 39, which are compressed betweenthe shoulder 40 and the rear ends 38 of the friction shoes, affording ahigh compression resisting capacity to the draft gear.

I claim l'. In a railway draft rigging, a compression resisting membercomprising a friction shell, .a wedge, friction shoes, springs andresilient disks within the shell, the shell being provided with aninternal shoulder between which and the rear end of the friction shoesthe resilient disks are compressed upon the full compression of thespring.

2. In arailway draft rigging, a compression resisting device comprisinga friction shell provided with an internal annular shoulder in front ofwhich the shell is of a larger internal diameter than back of the saidshoulder, and a wedge, friction shoes, springs and resilient diskswithin the friction shell, the springs being seated at their rear endagainst the internal rear face of the friction shell, and at their:forward end against the said disks, the disks being between the rear endof the friction shoes and the said springs, andbeing capable of fullsionresisting member comprising a shell, friction mechanism, friction shoesand springs within the shell, a resilient member interposed between saidsprings and friction mechanism, said shell being provided with a seatbetween which and the friction shoes the said resilient member isengaged and adaptedto be compressed.

4;. In a railway draft rigging, a compression resisting membercomprising a shell, friction mechanism and springs within the shell, aresilient member interposed between said springs and the frictionmechanism, said shell having an internal seat against which thesaidresilient member is compressed by the friction mechanism aftercompressing movement ofthe springs.

' 5. In a draft gear, a shell having an internal shoulder in front ofwhich the shell is of larger internal Width than back of said shoulder,a wedge, friction shoes and a resilient member within the shell andsprings, the said resilient member being seated between the frictionshoes and said springs, the said resilient member being adapted to movewiththe friction shoes, and to be comressed thereby upon engaging saidshoul- WILLIAM H.
